CAlling a sp outside a transaction

[Thierry Bertin]

Hello,

So I explain,.....

A sp, named spc_A, is called from a COM component and that COM
component is transactionnal.

So a transaction is open and spc_A called an another sp, named spc_B.

spc_B make a update on a table and go back to spc_A.

After that spc_A raise an error and the COM component rollback the
transaction.

My question is, how does execute the spc_B to not rollback the update
on the table ?

Thanks a lot
